Application filed December 28, 1904. Serial No. 238.631.

.Figure 1 is a side elevation of a grindingnull embodying this invention. Fig. 2 is a view like Fig. 1 in section. Fi 3 is an end view of Fi 1. Fig. 4 is an e ge view of a section of t e mill. d

' In the drawin s is shown a case composed of sections 0,. his case is supported on wheels b of shafts c. A suitable pulley or driving means rotates the wheels or some of them so as to cause the case or shell a to roll or rotate. This motion is easy and requires small expenditure of force. In this rotary case 1s a crusher or weight. This crusher is composed of sections d, connected to ether by suitable means to allow a certain ooseness or play to the sections with respect to one another, but compelling the crusher-sec- This crusher is loose in and of less diameter than the case so. as to roll upon the inner'surface thereof. These crusher-sections are shown hollow or tubular, and each section has a web etherein. A link-bolt f being connected or secured to each web and these links engaging one another these sections are united or made to move in unison.

The adjacent faces or the part ofA each crusher-section which faces the other is shown roughened or corrugated. The outline or taper of the crusher or wei ht d is "different from that of the case. Suc non-conformance, as seen in Fig. 2, causes the adjacent crusher-faces to ga e or be out of parallel. The rolling of tIhe crusher causing these faces to move parts to and from one another material entrapped between the sections or cau ht or seized by the corru ations or teeth wil be comminuted orcrus ed or carried about.

The case is shown tapered from its center portion in each direction in the axis 0f rotation. The crusher is likewise tapered, but in different degree. The case has an entrance and exit at g and h, respectively. These yopenings or mouths allow continuous flow or passage of water or fluid durin operation A or while the case is rotating.` T e tubular form ofthe crusher-sections also allows flow through the ap aratus.

A cover 'i is shown for a withdrawing-opening. This cover can be held removably in place by suitable means. 'A cross-piece ory rod k, engaging lugs or eyes m on the case and provided with a screw, can hold the cover in place in the opening of the case.

The meeting rims of the case-sections are shown as flan es with groove-sections for a packing n, suc as a piece or ring of rubber or -other suitable material. The flanges being bolted directly together or metal'coming to metal the bolting canbe firmly made. At

the same time the packing revents leaka e..

By having the 1nlet g gher or sma er than outlet h no backflow can occur, but water entering atg will pass off at h.

As the case is supported at'four points by the four rotary wheels b, said case needs no other -suplports or gudgeons to maintain the 'same 1n ace.

Whatclaim as my invention, and desire to secure by Letters Patent, is

1. A grindingmill comprising a rotary case tapering from the center toward eac end, and a crusher arranged within'the case and composed of iieXibly-connected sections of a conlcit different from that ofthe case and adapte to grind or comminute material betweentheir adjacent faces, each of said crusher-sections ta ering from the inner toward the outer en thereof and conforming in contour to the shape of the casing so as to nest therein and prevent displacement of the crusher during rotation of the casingl, the taper of the crusher being of somewhat ifferent de ee to the ta er of the case so as to cause t e meeting edges of the crusher-sections to gape or stand at an angle to one another; I

2. A grinding-mill comprising a rotar case tapering from the center toward eac end, and a crusher arranged within the case andcomposed of sections of a conicity diHerent from that of the case linked together and adapted to grind or. comminute material between their adjacent faces, each of said crusher-sections tapering from the inner toward the outer end thereof and conforming in contour to the shape of the casing so as to IIO l Crusher during rotation of the. casin the taper ofthe crusher being of somewhat iiferent degree to the taper of the case so as to c ause the meeting edges of the Crusher-sectlons to gape or stand at an angle to one an other.

3. In a grinding-mill a rotary case and tubular or open Crusher-sections each having a web in its ulterior clear of the edges, and linkbolts res ectively secured to the webs an connecte to one another.

4. In a grinding mill, a tapered rotary case and Crusher-sections of different taper than the case and having their opposing end faces corrugated.

5. In a grinding-mill a rotary case tapering from the center toward each end and having openings along the axis of rotation and Crusher-sections of tubular shape placed end to end and extended in like direction so as'to allow flow during the ofperation through the Crusher and both ends o the case.

6. In a grinding-mill a rotar case tapered from its center portion in eac direction in. the axis of rotation, tubular or hollow Crushersections of different taper from the case, and a connection between the sections, said case having openings for the passage of Huid during operation and a withdrawing-opening with cover therefor, said Crusher-sections being placed end to end and being detached from the case so as to rollfreely therein.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
